yeah, as others have mentioned, it's not the age, but the storage conditions. Right now JR is selling 10 yr old "vintage" Montecristos at a significant markup.
That being said, what is the humidity like where you live? I'm in Houston where the Humidity stays between 70-100% year round, so I could probably leave a cigar out of the humi for 10 years without it drying out completely. In fact, I have to keep my cigars in the tuppperdor, not to keep them from drying out, but to keep them from getting too moist.
You will want to re-humidify them before they get smoked, but who knows? They could be great.
enjoy!
